In article said:Hi all,
In order to get myself to run (I don't like running) I've
signed up for a 5K race. Nothing works as well as fear for
me when it comes to motivation. A fear of not finishing or
not showing a good time, it does not matter. Anyway, the
idea worked and I am running every day.
The race day is comming up and my question is about the
race pace. I am very slow, so the absolute speed is
irrelevant. But what I want is to do the race at the
optimum speed for me: being able to finish while not going
slower than I can go. I am guessing this is a universal
goal for all racers.
Is there any rules of thumb as far as what to aim for pace-
wise as related to heart rate? For example (is this the
same for everyone?), at 80% of my MHR I can last forever,
at 85% MHR, I will get tired, but don't know how long I
would be able to last, at 95%+ MHR, I die quick.
I don't know if you remember this, but I posted heartrate
data for you on mfw some time back. I think I was about 90%
after 2 minutes, 95% after 2 and indistinguishable from 100%
from mile 2 onwards.
The problem is that MHR depends on conditions, so it's hard
to distinguish between 95% and 97% of your true MHR. In
other words, don't use a heart rate monitor for the race
unless you want to run slowly.
Quoted message said:But races are different than training. It is OK to kill
yourself in a race (not literally). So what do most
people do? Find steady pace that will last the 5K. Start
out easy and sprint the last mile? How do you find the
ultimate pace?
The optimal pacing for a 5k is an even pace, with a strong
final 400m or so.
Quoted message said:I understand that you can arrive at the ultimate pace with
lots of trial and error,
Which is, to a large extent, what you use. You need sharp
racing instincts to run a really good race and these come
with experience.
Quoted message said:but I don't have much time left (race is in a week). I
don't need to come up with a perfect formula here. Just
something that will give me a reasonable performace that I
can try to beat later.
Since you're fairly new to this -- my suggestion would be to
hold back a little in the first mile. The excitement of the
race is likely to push you out the door quickly and running
along a lot of others tends to distort ones sense of pace.
It's very easy to start too quickly in a race setting.
Starting too quickly is more costly than starting too
slowly. If you start a little slowly, you can probably get
back 30 seconds by running a strong last mile, maybe even 10
seconds or more on the last 400m.
By the half way mark, you should be at a stage where you're
in just enough pain to be able to sense what the proper
pace is, and from there, it's a steady push to the finish
line. Getting to the halfway mark at the right pace is the
hard part.
My suggestion would be to go easy in the first half and push
hard in the last half of the race (OK, you don't know
exactly where the half way mark is but you know, it's a few
minutes after the 1 mile mark). If you finish with negative
splits (that is, you increase speed as the race progresses,
instead of dying halfway through), I think that's a
performance you can be proud of, and unless you start way
too cautiously, it will be a decent performance. I've always
felt good about races that I finished strongly, even the
ones that were not my fastest times.
Good luck.
Cheers,
